5 week old baby had bronchiolitis and therapy

Our baby is 5 weeks old. Had bronchiolitis and had therapy for 7 days in hospital in Macedonia with lendacin and urbason. now his chest are ok but continues with pulmicord inhaling (26 days) and Cefaklor sirup (5 days).
I am desperate for help what can i do to help our baby not to have side effects or further complications. I read that when babies are so young it is more then possible to have later complications or serious illnesses. Sometimes he screams like hell and we don’t know why. He might be in pain. He seems lost now, confused and scared from all the hospitals and needles :((
Please please please advice, what to do to help him.
